Hclip works on Windows, Mac OS X and Linux (but see the requirements below!). . Requirements: . * Windows: No additional requirements. . * Mac OS X: Requires the pbcopy and pbpaste commands, which ship with Mac OS X. . * Linux: Requires xclip or xsel installed. build-type: Simple cabal-version: >=1.10 library exposed-modules: System.Hclip other-extensions: CPP, DeriveDataTypeable, GADTs default-language: Haskell2010 build-depends: base >= 3 && < 5, process, mtl, strict if os(windows) build-depends: Win32 source-repository head type: git location: git://github.com/jetho/Hclip.git Hclip-3.0.0.4/LICENSE0000644000000000000000000000276012730340770012116 0ustar0000000000000000Copyright (c) 2013, Jens Thomas All rights reserved.
